As usual the product is effective with a very good look, even if there\'s more wind noise than on my previous car (Ford Focus) but this would be more related to BMW aerodynamics on the Active Tourer.
The installation is not so easy but if you take care everything goes well, next time I will plan to bought the wind deflectors from a reseller that will do also the installation.
My only fear is to remove them when I will change my car for the same one.
